Another note on 24:

Could it be that President Useless is such a mastermind that he had some involvement in the taking out of President Keeler. He was the VP and would stand to gain alot from Keeler being taken out.

I hadn't even thought about this until last night when I was thinking about how much I hated Logan last season and the beginning of this season and how much more I hated him after I found out about his involvement.

Do you think Useless could have ordered the killing of President Keeler?

INFORMATION FOR PEOPLE WHO DID NOT SEE LAST SEASON:
After President Palmer decided not to run for a second term, his opponent won the election, President Keeler. He was basically the polar opposite of Palmer on all policies. In the middle of the season, Air Force One was shot down by the terrorists. President Keeler was on board and was severely injured and assumed dead. Logan, the current president, was Keeler's VP and took over for him when his plane was taken down.

That still might now explain enough to help anyone.
